Half-time: Norwich 0 Chelsea 2 – Kenedy and Costa put Blues in control

Kenedy put Chelsea ahead after just 39 seconds at Carrow Road and Diego Costa netted a controversial second on the stroke of half-time.

Kenedy burst in from the left, dodged two challenges and fired into the far corner – his first Premier League goal.

The 20-year-old Brazilian replaced the axed Baba Rahman at left-back, while Bertrand Traore was brought in by boss Guus Hiddink for his first league start for the Blues.

There were also recalls for Oscar and Nemanja Matic, with Willian and John Mikel Obi dropping to the substitutes’ bench, where they are joined by Alexandre Pato, who was included in the matchday squad for the first time since his loan move.

Traore might have made it 2-0 had he managed to control Eden Hazard’s pass, but his heavy touch simply nudged the ball into the arms of Norwich keeper John Ruddy, who was also able to tip over Cesc Fabregas’ free-kick.

But the exciting Traore made amends by setting up Costa, who was in an offside position.

The goal was allowed to stand after the Chelsea striker lifted the ball over Ruddy – his 10th goal in his last 14 matches.

Chelsea, unbeaten in the league since Hiddink took over, have been well on top but were given a scare when Cameron Jerome headed over from Wes Hoolahan’s cross.
